From Podcast To Mushroom Coffee

One of my favorite daily routines is listening to podcasts, especially when I was out walking my client pups and driving back and forth between them.

Some of those shows are about blogging how to’s and branding.

Others deal with entrepreneurial journeys, leadership lessons as well as tips and tricks to make the best out of every day.

Tim Ferriss (The Tim Ferriss Show), Pat Flynn (Smart Passive Income Podcast), Andrew Warner (Mixergy), Jocko Willink (Jocko Podcast), & Darren Rowse (ProBlogger) are just some of the podcast hosts whose voices I’ve become super familiar with.

I’ve been learning massive lessons from all of them.

And today, I want to share one of my newfound health hacks with you all – brain boosting Mushroom Coffee created by Finnish entrepreneurs Four Sigmatic. 

They used to be one of Tim Ferriss’ sponsors that I kept hearing about several times per week for about 6 months.

That’s how long it took me finally pull the trigger and place my first order with them.

I’ve been ordering from them EVER SINCE 2018 and the only regret I have is that I didn’t buy their delicious concoction sooner.

By the way, in case you want to put a face to Tim Ferriss’ name, he talks about his favorite “smart drugs” in the video below.

The Mushroom coffee is the second one he mentions.

The 4 Ingredients in Four Sigmatic’s Mushroom Coffee

Mushroom coffee is a mix of the following 3 ground mushrooms and organic arabica instant coffee (50mg per serving):

  • Lion’s Mane (250mg per serving)
  • Chaga (250mg per serving)
  • Rhodiola Root (100 mg per serving) 

The arabica coffee is organically grown in the volcanic soil of the Sierra Madre de Chiapas highlands in Mexico.  

The rhodiola roots are wild-harvested from the mountains of Tibet and then extracted. 

The website doesn’t say where the Chaga & Lion’s Mane are from, so I’m going to assume they’re grown in the US.

It does say that they’re organically grown.

What Are The Benefits of Mushroom Coffee?

The Mushroom Coffee comes with a ton of health benefits:

  • Coffee itself is a great antioxidant, but you probably already knew that.
  • Chaga lowers acidity & boosts the immune system.
  • Lion’s mane boosts brain function & creativity.
  • Rhodiola root is an adaptogenic herb that increases resistance to stress & also boosts brain function.

Adaptogens are herbs that help the body adopt to stress, both physically and emotionally.

I’ve definitely noticed that I’ve become more stress resistant since drinking the mushroom coffee and also more mellow in general. I can also attest to the cognitive enhancement. 

It really does give my brain a boost when I need to deliver, both physically when I had to juggle my client pups and also mentally when I’m blogging or writing copy for clients.

What Does Mushroom Coffee Taste Like?

Delicious is what it tastes like!!

Over the years, I ran out of the mushroom coffee a few times and had to go without it for a few days.

BOY, did I miss that yummy concoction.

But on a more serious note, it has a fruity flavor and is mild and smooth.

It’s a lot less acidic than regular coffee and definitely does not taste like mushrooms at all. 

The beautiful side effect for me is that I no longer get any jitters from drinking too much coffee and I’m also no longer bothered by acid reflux.

Love it!

How To Make The Coffee

Four Sigmatic’s Mushroom Coffee is super easy to make – all you need is hot water.

Just pour it over a small spoonful of the mushroom coffee, stir, and that’s it.

I like to add a little almond milk, but it also tastes great as is.

I typically have 2 or 3 cups of it per day.

Four Sigmatic suggests drinking it “whenever your brain needs an energizing get-it-together hug.”

Update 2024: Four Sigmatic’s Instant Mushroom Coffee is now also available as ground coffee for pour overs.

Any Cons?

The only con I can come up with is the mushroom coffee’s price point.

10 single packets are $15, but there is the option of saving 20% on every single order if you set up a subscription.

It’s what I ended up doing after I tried a month’s worth of the single packets. 

Back in the States, I got the mushroom coffee delivered in a tin every 6 weeks, which cost me $32 (regular price is $40).

Now that I live in Germany, I have a subscription for the Four Sigmatic mushroom coffee beans.

I get one 12 oz = 340 g bag per month, which costs me just shy of €17, so just a little over $18.

Since I have a recurring monthly subscription, I save 25%.

Thank goodness that they deliver here!!

I was seriously worried about that when we moved from the US to Germany.

Mushroom Coffee Boosts This Dog Mom’s Brain Power & Creativity: Bottom Line

The mushroom coffee isn’t the least expensive coffee out there, but I consider it an investment in my own health. 

I’ve become a lot more conscientious of what makes it into my body ever since I incorporated a variety of lifestyle changes after my beloved puppy Missy was diagnosed with cancer for the first time in 2014. 

I figured that the less processed food approach and use of smart drugs (I’m thinking turmeric paste, raw goat milk, green lipped mussels) would not only benefit her (& her brother Buzz), but also me.

I love that this coffee falls into the “smart drug” category and that it acts as a cognitive booster while cutting out the jitters & acidity of my former coffee drinking habits.


Enthusiastically recommended! Do yourself a favor and try it!
